Question 900952: A person says that his son is 5 times as old as his daughter and his wife is 5 times older than his son and he is twice the age of his wife . The sum total of all the ages equals the age of the grand mother who celebrated her 81st birthday today.
How old was his son?

You can put this solution on YOUR website! Taking the daughter's age to be x, we get
the son's age to be 5x
the wife's age to be 25x and
the his age to be 50x.
So according to question,
x + 5x + 25x + 50x = 81
or, 81x = 81
or, x = 1
Thus, the age of the son is 5 years old.
